The package presents itself as 'Development utility helpers' but its main module executes an IIFE at require-time that issues an Image request to http://5.189.173.113:8899/csp-edu with document.domain appended as a query parameter. A sibling file bypass.js contains an equivalent beacon to http://5.189.173.113:8899/csp. Both destinations are a hardcoded bare IP over plain HTTP, unrelated to any advertised functionality, and receive host-context data (the consuming page's domain) whenever the module is loaded.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
